Uhm, where should I sign up to post to your forum?
Can you please try to redownload the plugin again?
That’s the first thing I did when I encountered the error: I deleted and re-installed the plugin from scratch, using the latest available version (3.0.5). I will post the error in the official plugin forum, as suggested. Thanks.
I was using the latest available version of Tweetable at the time I posted. If the widget bug has been fixed since then, I will try to reinstall it. Thanks.
